The Lowdown

Alright, let's talk surf. This stretch has some gems, but you gotta be ready to move when the window opens.

We start on Tuesday, September 8th at Jaconé. Morning brings a solid 5 ft south swell. The wind is out of the ENE at 9 mph, blowing offshore, making it clean. The combined energy sits at 829 (moderate wave energy). That's a good, solid wave for an intermediate surfer. The water feels about average for this time of year. Afternoon wind picks up but stays cross-offshore, still clean, though the swell eases a bit. Crowds are a possibility here, so don't be surprised if you have company.

Wednesday the 9th looks good again in the AM. Swell is up to 6 ft, but the period is short at 7 seconds, coming from the ENE. The offshore wind is a whisper at 3 mph, keeping it smooth. That short period will make it a bit junky, but you can still have fun. Afternoon turns to junk with rain and onshore wind, so wrap it up early.

Thursday the 10th is a classic. Swell drops to 4 ft, but the period stretches to 12 seconds – a proper groundswell. And the wind is glassy, both morning and afternoon. This is perfect for a longboard or a fish. The energy is moderate (440). It won't be big, but it will be ridiculously clean and fun.

Now, Friday the 11th is the day to circle. Morning shows a 4 ft south swell, a very long 14-second period, and a crisp offshore wind from the NNE at 9 mph. This is a standout. The combined energy jumps to 1011 (strong wave energy). For the experienced surfer, this is top-tier. The afternoon turns completely glassy with no wind and a 4 ft swell. If you can swing either session, do it.

Saturday the 12th is a total washout with onshore wind and rain.

Sunday the 13th is tricky. Morning shows a big 8 ft SSW swell, but the period is just 10 seconds. The energy is high (1066 (strong wave energy)). The wind is cross-shore, so there will be some bumps. This is pushing into expert-only territory. The afternoon cleans up with a cross-offshore breeze and the swell dropping to 5 ft.

Into the second week, Monday the 14th is for the big dogs. We’re looking at 8 ft SSE swell with an 11-second period. The wind goes offshore from the NE, and the energy is pumping hard – 1753 (very strong wave energy). This is strictly for experts. If you have the skills and the nerve, the afternoon session will be heavy.

Tuesday the 15th and Wednesday the 16th settle back into the 4 ft to 5 ft range with clean, offshore, or glassy winds. Nice, consistent smaller days for the rest of us.

From Thursday the 17th to Wednesday the 23rd, it fades out. The swell gets smaller, the winds get messy. There’s a long gap in quality. There is a little bump on Sunday the 20th with a 3 ft south swell and a very long 14-second period blowing offshore at 18 mph – that's a fresh breeze, so it'll be clean but small and the wind could be bumpy on the faces. After that, it really goes tiny and ordinary. This kind of dry spell is pretty normal here when the pattern shifts.

So, the call is: Friday the 11th is the king of the period for quality and power. Thursday the 10th is your glassy, relaxed session. The big Monday the 14th is for the brave. After that, you're on watch until the next pulse.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
